Lakemont Estates Lake Dam dam
Lakemont Estates Lake Dam
Lakemont Estates Lake Dam, also known as Pine Grove Road Lake Dam, is a privately owned structure located in Roswell, Georgia. Built in 1966, this earth dam stands at a height of 28.7 feet and serves primarily for recreational purposes. The dam has a normal storage capacity of 71 acre-feet and covers a surface area of 7.4 acres, with a drainage area of 210 acres.
Despite being classified as having a low hazard potential, the dam has not been rated for its condition as of the last inspection in June 2017. It features an uncontrolled spillway type and outlet gates, with a hydraulic height of 23 feet. The risk assessment for Lakemont Estates Lake Dam is moderate, indicating a level 3 risk, though specific risk management measures and inundation maps have not been detailed.
Overall, the Lakemont Estates Lake Dam presents an interesting case study for water resource and climate enthusiasts, showcasing a privately owned recreational structure in Georgia with a rich history dating back to the 1960s. As efforts to assess and manage risks associated with dams continue to evolve, this dam serves as a reminder of the importance of regular inspections and maintenance to ensure the safety and functionality of such critical infrastructure.
Dam data reference
Condition Assessment
- Satisfactory
- No existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
- Fair
- No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action.
- Poor
- A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency.
- Unsatisfactory
- A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
- Not Rated
- The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Hazard Potential Classification
- High
- Dams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
- Significant
- Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environmental damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
- Low
- Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
- Undetermined
- Dams for which a downstream hazard potential has not been designated or is not provided.

About Lakemont Estates Lake Dam
Where does the data for Lakemont Estates Lake Dam come from?
Structural and regulatory data come from the U.S. Army Corps of Engineers' National Inventory of Dams (NID). Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.
How often is the report updated?
NID structural data refreshes annually as the Corps publishes updated assessments. The weather forecast refreshes throughout the day.
What does the Low hazard rating mean?
The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card above for the full definitions.
What's "% of normal"?
The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).
Can I get alerts when storage crosses a threshold?
Yes -- alerts are managed in the Snoflo iOS app. Favorite this dam, set a threshold, and you'll get a push the moment conditions cross.
